Fix bugs in Octeontx2 netdev driver
In existing Octeontx2 network drivers code has issues
like stale entries in broadcast replication list, missing
L3TYPE for IPv6 frames, running tx queues on error and
race condition in mbox reset.
This patch set fixes the above issues.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
Mbox implementation in octeontx2 driver has three states
alloc, send and reset in mbox response. VF allocate and
sends message to PF for processing, PF ACKs them back and
reset the mbox memory. In some case we see synchronization
issue where after msgs_acked is incremented and before
mbox_reset API is called, if current execution is scheduled
out and a different thread is scheduled in which checks for
msgs_acked. Since the new thread sees msgs_acked == msgs_sent
it will try to allocate a new message and to send a new mbox
message to PF.Now if mbox_reset is scheduled in, PF will see
'0' in msgs_send.
This patch fixes the issue by calling mbox_reset before
incrementing msgs_acked flag for last processing message and
checks for valid message size.

Jonathan reports that the strict policy for memory mapped by the
ACPI core breaks the use case of passing ACPI table overrides via
initramfs. This is due to the fact that the memory type used for
loading the initramfs in memory is not recognized as a memory type
that is typically used by firmware to pass firmware tables.
Since the purpose of the strict policy is to ensure that no AML or
other ACPI code can manipulate any memory that is used by the kernel
to keep its internal state or the state of user tasks, we can relax
the permission check, and allow mappings of memory that is reserved
and marked as NOMAP via memblock, and therefore not covered by the
linear mapping to begin with.

The NoMMU kernel is broken for QEMU virt machine from Linux-5.9-rc6
because clint_time_val is used even before CLINT driver is probed
at following places:
1. rand_initialize() calls get_cycles() which in-turn uses
clint_time_val
2. boot_init_stack_canary() calls get_cycles() which in-turn
uses clint_time_val
The issue#1 (above) is fixed by providing custom random_get_entropy()
for RISC-V NoMMU kernel. For issue#2 (above), we remove dependency of
boot_init_stack_canary() on get_cycles() and this is aligned with the
boot_init_stack_canary() implementations of ARM, ARM64 and MIPS kernel.

We use a device's allocation state tree to track ranges in a device used
for allocated chunks, and we set ranges in this tree when allocating a new
chunk. However after a device replace operation, we were not setting the
allocated ranges in the new device's allocation state tree, so that tree
is empty after a device replace.
This means that a fitrim operation after a device replace will trim the
device ranges that have allocated chunks and extents, as we trim every
range for which there is not a range marked in the device's allocation
state tree. It is also important during chunk allocation, since the
device's allocation state is used to determine if a range is already
allocated when allocating a new chunk.
This is trivial to reproduce and the following script triggers the bug:
$ cat reproducer.sh

If the driver initializes in safe mode, it will call
ice_set_safe_mode_caps. This results in clearing the capabilities
structures, in order to set them up for operating in safe mode, ensuring
many features are disabled.
This has a side effect of also clearing the capability bits that relate
to NVM update. The result is that the device driver will not indicate
support for unified update, even if the firmware is capable.
Fix this by adding the relevant capability fields to the list of values
we preserve. To simplify the code, use a common_cap structure instead of
a handful of local variables. To reduce some duplication of the
capability name, introduce a couple of macros used to restore the
capabilities values from the cached copy.

The ice driver needs to wait for a firmware response to each command to
write a block of data to the scratch area used to update the device
firmware. The driver currently waits for up to 1 second for this to be
returned.
It turns out that firmware might take longer than 1 second to return
a completion in some cases. If this happens, the flash update will fail
to complete.
Fix this by increasing the maximum time that the driver will wait for
both writing a block of data, and for activating the new NVM bank. The
timeout for an erase command is already several minutes, as the firmware
had to erase the entire bank which was already expected to take a minute
or more in the worst case.
In the case where firmware really won't respond, we will now take longer
to fail. However, this ensures that if the firmware is simply slow to
respond, the flash update can still complete. This new maximum timeout
should not adversely increase the update time, as the implementation for
wait_event_interruptible_timeout, and should wake very soon after we get
a completion event. It is better for a flash update be slow but still
succeed than to fail because we gave up too quickly.

This reverts the parts of commits

0fb8125635 that touch paths outside
of drivers/gpu/drm/pl111.
The fbdev driver is used by Android's FVP configuration. Using the
DRM driver together with DRM's fbdev emulation results in a failure
to boot Android. The root cause is that Android's generic fbdev
userspace driver relies on the ability to set the pixel format via
FBIOPUT_VSCREENINFO, which is not supported by fbdev emulation.
There have been other less critical behavioral differences identified
between the fbdev driver and the DRM driver with fbdev emulation. The
DRM driver exposes different values for the panel's width, height and
refresh rate, and the DRM driver fails a FBIOPUT_VSCREENINFO syscall
with yres_virtual greater than the maximum supported value instead
of letting the syscall succeed and setting yres_virtual based on yres.

This does introduce two merge conflicts with net-next, but both have

autofs got broken in some configurations by commit 13c164b1a1
("autofs: switch to kernel_write") because there is now an extra LSM
permission check done by security_file_permission() in rw_verify_area().
autofs is one if the few places that really does want the much more
limited __kernel_write(), because the write is an internal kernel one
that shouldn't do any user permission checks (it also doesn't need the
file_start_write/file_end_write logic, since it's just a pipe).
There are a couple of other cases like that - accounting, core dumping,
and splice - but autofs stands out because it can be built as a module.
As a result, we need to export this internal __kernel_write() function
again.
We really don't want any other module to use this, but we don't have a
"EXPORT_SYMBOL_FOR_AUTOFS_ONLY()". But we can mark it GPL-only to at
least approximate that "internal use only" for licensing.
While in this area, make autofs pass in NULL for the file position
pointer, since it's always a pipe, and we now use a NULL file pointer
for streaming file descriptors (see file_ppos() and commit 438ab720c675:
"vfs: pass ppos=NULL to .read()/.write() of FMODE_STREAM files")
This effectively reverts commits 9db9775224 ("fs: unexport
__kernel_write") and 13c164b1a1 ("autofs: switch to kernel_write").
Fixes: 13c164b1a1 ("autofs: switch to kernel_write")

====================
via-rhine: Resume fix and other maintenance work
I use via-rhine based Ethernet regularly, and the Ethernet dying
after resume was really annoying me. I decided to take the
matter into my own hands, and came up with a fix for the Ethernet
disappearing after resume. I will also want to take over the code
maintenance work for via-rhine. The patches apply to the latest
code, but they should be backported to older kernels as well.

In rhine_resume() and rhine_suspend(), the code calls netif_running()
to see if the network interface is down or not. If it is down (i.e.,
netif_running() returning false), they will skip any housekeeping work
within the function relating to the hardware. This becomes a problem
when the hardware resumes from a standby since it is counting on
rhine_resume() to map its MMIO and power up rest of the hardware.
Not getting its MMIO remapped and rest of the hardware powered
up lead to a soft reset failure and hardware disappearance. The
solution is to map its MMIO and power up rest of the hardware inside
rhine_open() before soft reset is to be performed. This solution was
verified on ASUS P5V800-VM mainboard's integrated Rhine-II Ethernet
MAC inside VIA Technologies VT8251 South Bridge.

Commit 78fe9f6394 ("drm/amd/display: Remove DISPCLK Limit Floor for Certain SMU Versions")
added a call to rn_vbios_smu_get_smu_version() to set clk_mgr->smu_ver.
That field is initialized prior to the if-statement, already.

A recent attempt to fix a ref count leak in
amdgpu_display_crtc_set_config() turned out to be doing too much and
"fixed" an intended decrease as if it were a leak. Undo that part to
restore the proper balance. This is the very nature of this function
to increase or decrease the power reference count depending on the
situation.
Consequences of this bug is that the power reference would
eventually get down to 0 while the display was still in use,
resulting in that display switching off unexpectedly.

When building with
$ HOST_EXTRACFLAGS=-g make
the expectation is that host tools are built with debug informations.
This however doesn't happen if the Makefile assigns a new value to the
HOST_EXTRACFLAGS instead of appending to it. So use += instead of := for
the first assignment.
